1 Claim.

This application is a division of my former application for patent filed August 20, 1932, Serial No. 629,699, for Edge rolls.

The objects of this application are:

First, to provide a cord or edge roll for finishing the edges of parts of furniture in which the soft core is a soft resilient fibrous substance and in which there is a reinforcing edge that may be cheaply and easily made.

Second, to provide such a cord with a reinforcing portion through which stitches or nails may be inserted without tearing the cord.

Third, to provide an edge roll with attaching web that can be cheaply and easily assembled and will withstand the attaching because of properly placed reinforcing.

Other objects and advantages of my invention will appear from the description to follow. Preferred embodiments of my invention are illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of a hat of jute or other suitable material for use in making such a cord.

Fig. 2 is a perspective view of a section of the cord with the end portion of the material released from the braided covering threads.

Fig. 3 is a side elevation of such a cord.

Fig. 4 is a view of the finished cord shown with a nail extending therethrough for attach- I ing.

The parts will be identified by their numerals of reference which are the same in all the views.

1 is a bat of jute fibers or other fibers suitable for manufacturing my improved cord. 1, have found that jute is successful because it possesses the necessary qualities of softness and resiliency. It is possible to use hair that has been gametted and made into bats or cotton or any similar material. The bat is cut into strips 2 which are rolled or folded as is shown in Fig. 2 or may be run directly to the forming die. The strip 2 is then passed through a forming die where it is compressed to a substantially cylindrical form. If desired, the forming die may impart different forms to the cord so as to form an attaching web thereon or to give oval or other form to the cord.

It will be understood that if desired two or more bats of the material may be run through the forming means to form a cord of the desired shape. These bats may be of diiferent sizes if desired, it being important only that the desired form of cord be produced.

3 is a strip of burlap or other fabric used to reinforce the cord. The strip partially covers the fibrous material and is shown here oi. a

-width sufllcient to receive stitches or nails to attach the cord to the furniture.

The strip 3 is arranged longitudinally of the cord by placing the strip 3 on the strip 2 as it goes into the forming die. A guide is used to prevent spiraling of the strip, and it is pressed against the fibrous material as the cord is formed. The cord passes from the forming die to a braiding machine where it is covered with light threads 4 which retain the fibrous material in the desired shape and also retain the strip in position on the finished cord.

It will thus be seen that the cord thus produced is much stronger than the cord without such a reinforcing strip and nails or stitches will not tear out as easily as they would if the fibrous material and the cords were depended upon entirely. The cord may be very cheaply made without any additional labor and the burlap strip adds little to the cost.

Instead of jute or hair or other fibrous material, it is possible to use wadded crepe sheets of cellulose as is fully described in my Patent No. 1,821,582, issued September 1, 1931, for Packing cord.

An attaching web may be formed on the cord to make a pre-formed edge roll by running a row of stitches 11 longitudinally of the cord and through the reinforcing strip 3 as is shown in Fig. 4. The cord can be fed to a sewing machine through a proper die to form the web and the stitching pinches the material to retain the formed web.

It will be noted that the stitching 11 passes twice through the burlap reinforcing strip. This assures a firm attaching web because the stitching cannot pull out through the burlap reinforcement.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

An edge roll comprising resilient material compressed to form, a fabric reinforcing strip disposed longitudinally of and covering a portion only of said material, braided wrapping threads embracing said material and said strip, and a longitudinal row of stitches passing twice through said strip and through said material, whereby an attaching web is formed.
